ICT321 Architecture and Systems Integration Assignment 2 Page 3 of 6 Case Study: System Integration for Dell After evaluating various platforms, Dell finally decided to adopt Service Oriented Architecture (SOA) for its future IT infrastructure. The EA team also noticed the trends of new technologies including data analytics, cloud-based services, social media, and mobile computing. It was a shared belief that that the business functionalities delivered by services will reduce the technical obstacles to embrace these new technologies. The EA team needed to figure out the following issues:

1. Computing and storage infrastructure design. There are three possible options: renting from public Cloud providers, building a private Cloud, or maintaining its current infrastructure distributed across various locations and business units. Which one should the company choose? What are the benefits of the selected solution, and how does it support the IT operations? You are also encouraged to propose a different solution other than the previous list (Optional).

2. Application/service integration. There are different types of applications and services coexisting in the company, including legacy applications, internal Web services, and external Web services. Some external services are provided by business partners, and others are from public service providers, such as Google Map and Google Search. General solutions for application integration should be discussed, and a demo system (see below) is also expected to be implemented.

3. Information integration. Currently, there are multiple data sources developed by different teams for various business units and departments. Some databases will be unified and merged to replace existing system. However, some data sources have to be maintained individually due to the existence of legacy systems. In either case, how data from difference sources can be integrated should be discussed. In addition, a demo system (see below) is expected to be implemented. To demonstrate the ideas of application and data integration, the EA team decided to build a demo system to validate their designs.

Advantages and Challenges of SOA

The demo enables customers to search the locations of retailers in Google Map. There are three major components in the demo system:

1. Data integration demo. In this demo, there are two data source files: “stores.csv” contains the information about stores, and “locations.xml” contains the information about the location coordinates for each store. A Python scrip file with the name “data_merger.py” should be implemented to read these two data files, and output the merged result into a CSV file with the name “store_locations.csv”.

2. RESTful Web service demo. In this demo, we need to build a RESTful Web service which returns a JSON object with three attributes (storename, latitude, longitude) when receiving a call similar to “/getlocation?postcode=xxxx”. The framework Bottle is recommended for this implementation. A Python scrip file with the name “store_locator.py” should be implemented to retrieve the correct data from “store_locations.csv”, and to return the value via Web Service.

3. Mashup demo. In this demo, we need to build a mashup application which accepts a postcode as the input. If a store in that suburb can be found, then its location is displayed in Google Map. Otherwise, the default store (with postcode 2000) is ICT321 Architecture and Systems Integration Assignment 2 Page 4 of 6 displayed.

A HTML file “store_map.html” should be implemented. In this file, a text field is provided at the page top to accept user’s input of postcode. In addition, a Submit button will trigger the “getlocation” Web Service to retrieve its corresponding latitude and longitude, and highlight and centre the location in Google map. You need to include a section in the report to explain the key points for the demo design and implementation. Moreover, you need to explain how to run your demo/code. With regard to the above requirements, implement a demo system (30%) and write a technical report (70%).

Please use the following outline in your report:

1. Introduction

2. Computing and storage infrastructure design

3. Application/service integration

4. Information integration

5. Demo introduction

Service-Oriented Architecture (SOA) and Web services APIs

Access to capacity is made conceivable through a Web administrations application programming interface (API) utilizing the various WS protocols for example, Simple Object Access Protocol (SOAP) or Representational State Transfer (REST) convention. The foundation is regularly worked with ware equipment and servers are grouped so the capacity limit of each can be collected into a solitary pool. In this foundation arrangement, limit development is made conceivable by adding another server to the bunch. 

Computing and storage infrastructure design 

It demonstrates structural model of a versatile Cloud stockpiling framework. It comprises of the accompanying segments:

• VM-facilitating machines: A physical machine has countless and has constrained nearby storage room. vStore utilizes nearby capacity as a piece level reserve and gives to VMs the figment of boundless storage room. 

• Storage Server Cluster: Storage server groups give arrange appended capacity to machines present physically . They could also be either committed elite stockpiling servers or a group of servers utilizing item stockpiling gadgets. 

• Directory Server: The catalog server holds the area data about the capacity server bunches. At the point when a hypervisor needs to interface with a particular stockpiling server.

Application/service integration 

The greatest advantage of SOA is adaptability. A SOA enables the endeavor to rapidly change its framework in light of changes in the business condition, on the grounds that a large portion of the fundamental procedures are as of now accessible as Web administrations. New usefulness can be created as a Web benefit and connected back to other fundamental business forms. The business can adjust and flourish. 

In the conventional application design, and rather than into the more present day universe of Web benefits, present foundation assets commonly bolster a particular application or association inside your venture. As you anticipate limit and execution, you can test the points of confinement of your framework assets and foundation with a genuinely decent comprehension of where the request will originate from and how it will be handled. With SOA, this kind of arranging and testing is all the more difficult on the grounds that your foundation assets may bolster a group of clients and applications through administrations spread all through your endeavor. 

While an essential advantage of SOA is that applications can be worked by joining inexactly coupled and interoperable administrations, the way that an administration might be generally utilized all through the endeavor by numerous applications can prompt the accompanying exposures for your IT foundation: 

• Poor reaction times for clients and business forms
• Missed administration levels for basic business capacities
• Noncompliance with industry and government controls
• Security breaks
• Inadequate administration
• Governance holes and restrictions
• Testing challenges 

Up to this point, your IT association has in all probability been centered around overseeing the foundation as a resource for help applications and specialty units. With SOA, your concentration needs to move toward dealing with the administrations which bolster business forms and, hence, business comes about. SOA changes the part of the IT framework. You will now need to deal with your IT assets so that the administrations that help the business can use that framework

Information integration

The issue is frequently portrayed by issues with no normal work process approach, an absence of information quality and information profiling capacities, modified change rationale extraordinary to every datum encourage, absence of continuous checking ability, and a failure to rapidly include new information nourishes.

Advantages and Challenges of SOA

Setting

Information should be imparted to new frameworks created on open frameworks and with other centralized server frameworks, both inside and outer to the association. Most inheritance frameworks have approaching or active information sustains.

Powers

Remain solitary applications and associations are relics of days gone by. The need presently is for data sharing amongst applications and organizations.
